Secret Rabbit Code (aka libsamplerate) is a Sample Rate Converterfor audio. One example of where such a thing would be useful isconverting audio from the CD sample rate of 44.1kHz to the 48kHzsample rate used by DAT players.

SRC is capable of arbitrary and time varying conversions ;from downsampling by a factor of 256 to upsampling by the samefactor. Arbitrary in this case means that the ratio of input andoutput sample rates can be an irrational number. The conversionratio can also vary with time for speeding up and slowing downeffects.

SRC provides a small set of converters to allow quality to be tradedoff against computation cost. The current best converter providesa signal-to-noise ratio of 97dB with -3dB passband extending fromDC to 96% of the theoretical best bandwidth for a given pair ofinput and output sample rates.
